Springs and swallow holes in karst regions

The Karst springs and swallow holes layer shows the main points where groundwater emerges from the karst system as well as important infiltration points. Distinctions are made between tapped and untapped as well as temporary and permanent springs. The karst springs are linked to the associated karst catchments: When a spring is selected, the catchment from which it is fed is highlighted. The information in the categories Karst regions and Karst groundwater, respectively, is based on hydrogeological 3D models (KARSYS approach). It was developed, with the support of the cantons, by the Swiss Institute for Speleology and Karst Studies SISKA and is published by the Federal Office for the Environment FOEN.喀斯特泉与落水洞图层展示了地下水从喀斯特系统涌出的主要点位，以及重要的入渗补给点位。该图层区分了已开发泉与未开发泉，以及暂时性泉与永久性泉。喀斯特泉与其所属的喀斯特汇水区相关联：当选中某一泉点时，其补给的汇水区将被高亮显示。“喀斯特区域”与“喀斯特地下水”两类数据的信息，均基于水文地质三维模型（KARSYS方法）。本数据集由瑞士洞穴与喀斯特研究学会（Swiss Institute for Speleology and Karst Studies, SISKA）在瑞士各州的支持下开发，并由瑞士联邦环境办公室（Federal Office for the Environment, FOEN）发布。
